Cosmic Ray induced instabilities in astrophysical systems
Free

1) Introduction
– Observational evidences of the presence energetic particles (or Cosmic Rays) in various astrophysical systems.
– Specific role of Cosmic Rays in astrophysical sources.
– The main category of Cosmic Ray induced instabilities
2) Two theoretical frameworks: the fluid theory and the Vlasov theory
3) Vlasov theory of plasma instabilities
– Normal mode analysis
– Instability analysis
4) Specific instabilities connected with the presence of Cosmic Rays
– The streaming instability
– The gyro resonant instability
– The firehose/mirror instability
– The acoustic instability
5) Recent numerical studies
– Numerical techniques: Particle-in-cell (or Vlasov), hybrid and kinetic-magnetohydrodynamics
– A survey of recent results (1986-2020)
